plants?
Answer:
Photorespiration is
associated with 
cycle,
where plant lose 
fixation
because of the increase in concentrate ion of 
and
change the nature of activity of RuBP carboxylase-oxygenase.
plants
have evolved a mechanism to avoid loss of .
There is not a direct contact of RuBP carboxylase-oxygenase as cycle
operates in bundle sheath cells (where both temperature and oxygen level low).
fixation
is done by another enzyme PEP carboxylase in mesophyll cells and oxaloacetate
is formed which is converted to malic acid and transported to bundle sheath cells.
There, it gives off which
is used in Calvin cycle, operating in bundle sheath cells of plants.
